File Browse button doesn't appear for File field in an array item about alpaca

[drq]

Give the following code a try. Basically you need to set the image field type in options. Other wise it will just render a text field that support url type value.

$(function() {
$("#field5").alpaca({
"schema": {
"description": "My Favorite Ice Creams",
"type": "array",
"items": {
"title": "Ice Cream",
"type": "object",
"properties": {
"flavor": {
"title": "Flavor",
"description": "Ice cream flavor",
"type": "string"
},
"topping": {
"title": "Topping",
"description": "Ice cream topping",
"type": "string"
},
"image": {
"title": "Image",
"description": "Ice cream topping image",
"type": "string",
"format": "uri"
}
}
}
},
"options" : {
"fields": {
"item": {
"fields": {
"image" : {
"type" : "file"
}
}
}
}
}
});
});
